We used to have a black lab, and all I remember is that he was about 11.5 pounds at 8 weeks, or somewhere around that maybe 12.

I think Jasper is also small for his age, because alot of boxer owners said that theres was 45-50 pounds at 6 months, thats big lol Jasper is about 35 and is 6 months.

But like you said, theyre healthy right? they'll grow
